Why is public key cryptography recommended for use in the process of securing facsimiles during
transmission?

A.
Keys are never transmitted over the network.

B.
Data compression decreases key change frequency.

C.
Key data is not recognizable from facsimile data.

D.
The key is securely passed to the receiving machine.

Explanation:
In this method of cryptography we use 2 keys, one to encrypt the data, and another
to decrypt it. In Public Key Cryptography, the users have a public and a private key, the public key
is of free distribution and is usually published in a directory, while the private keys must be keep
secure. This allows the keys to pass in a secure fashion to the receiving machine, its because the
public key is not confidential and can be send through a secure channel. You need to use a
certification authority to make this kind of cryptography work.
